#X text 153 405 Chains can make a surprisingly chaotic and unstable
sounding modulation or audio source. Coefficients of consecutive [vv~]
units can be independently varied for different effects \, and aren't
commutative.;
#X text 212 135 creation argument provides default value;
#X text 247 165 0 = correlation of 1 \, no variance \, i.e. constant.
1 = maximum variance \, same correlation as input \, i.e. 0 for uniform
white noise. low values are equivalent to a bounded random walk.;
#X text 228 226 This is "standardized" for Fs = 48000 I don't want
the behavior to be dependent on sample rate. At higher sample rates
\, variance of 1 won't reach the maximum. But I think it shouldn't
be audibly different than what you'd get at Fs = 48000;

#X text 357 94 this is taken to the fourth power for a more intuitive
control law \, but I don't have any solid theoretical justification
for doing this.;
